An opening range breakout (ORB) trades the first move beyond the high or low of the first minutes of the session. On NQ futures, our tests found the 15-minute range with a stop at the opposite side of the range worked far better than short ranges or tight stops — and that the edge depends on the market regime.
What is the opening range?
The opening range is the high and low of the first few minutes after the regular session opens at 09:30 Eastern. It captures the first auction of the day, when overnight orders, news reactions and the cash-market open all meet.
An opening range breakout waits for price to close outside that range and trades in the direction of the break, on the idea that the first decisive move often sets the tone for the morning.
Which settings mattered
We tested range lengths, stops, targets and filters on one-minute NQ data from 2014 to 2026, including trading costs, with entries filled at the next minute's open plus slippage. A few things stood out:
- Range length: the 15-minute range was clearly better than 5 or 30 minutes.
- Stop: a stop at the opposite side of the range beat tight stops by a wide margin. Tight stops get hit by normal noise before the move develops.
- Target: 1.0R, 1.5R, 2R and 3R produced similar results — the edge is mostly in the direction of the break, not the exit.
- Breakeven: moving the stop to entry after 1R helped slightly, because the target is fixed and close.
- Order-flow confirmation: skipping breaks where cumulative volume delta disagreed with the direction removed a group of trades that lost money in both test periods.
When it works best
The breakout had no edge in 2014–2020, even before costs. It has worked since 2021. That is typical of simple intraday rules: they depend on how the market behaves, and that changes. Treat any breakout rule as something to monitor, not something that works forever.
Fading failed breakouts (trading back into the range after a break fails) looked attractive in some periods but did not hold up across both periods in our tests. Combining the breakout with a fade made results worse than the breakout alone.
Past and simulated results don't guarantee future results. These findings describe how rules behaved on historical data and ignore many real-world frictions.
